Description

The A19350 is a giant magnetoresistance (GMR) integrated circuit (IC) that provides a user-friendly two-wire solution for applications where speed and direction information is required. The small integrated package includes an integrated capacitor and GMR IC in a single overmold design with an additional molded lead-stabilizing bar for robust shipping and ease of assembly.

Key Features

  • GMR technology integrates high sensitivity MR (magnetoresistive) sensor elements and high precision BiCMOS circuits on a single silicon integrated circuit, offering high accuracy, low magnetic field operation
  • Integrated capacitor in a single overmolded miniature package provides greater EMC robustness
  • SolidSpeed Digital Architecture supports advanced algorithms, maintaining performance in the presence of extreme system-level disturbances, including vibration immunity capability over the full target pitch
  • Flexible orientation for xMR or Hall replacement
  • ASIL B(D) rating based on integrated diagnostics and certified safety design process
  • Two-wire current source output pulse-width protocol supporting speed, direction, and ASIL
  • EEPROM offers device traceability throughout the production process 2 - PACKAGE: 2-Pin SIP (suffix UB) Not to scale
